  • How Nanotechnology Works

    How Nanotechnology Works

    Nanotechnology is so new, no one is really sure what will come of it. Even so, predictions range from the ability to reproduce things like diamonds and food to the world being devoured by self-replicating nanorobots. See more »

  • How Nanowires Work

    How Nanowires Work

    Welcome to the wonderful and weird world of nanowires. Scientists can adapt this incredibly thin material for a number of uses, whether as a fiber-optic nanowire or to build increasingly smaller microprocessors. They're even used in medical implants. See more »

  • How Plastics Work

    How Plastics Work

    Plastics can be shaped or molded into any form, and they're everywhere -- in your car, computer, toys and even bubble gum. But because they don't degrade, they cause big problems when it's time to throw them out. See more »
